Waves
What are three things that travel in waves?
Sound, light, energy
What are three properties of water?
Wave length, frequency, amplitude
Why does light break into patterns when it is run through thin slits?
they travel in different speeds, (different wave lengths)
Do X-rays have higher or lower frequency than light waves?
X-rays have a higher frequency than light waves
Define wavelength.
the length measure between 2 waves
What causes waves on the ocean?
Wind causes waves on the ocean
What are the waves in the earth called (earthquake waves)?
The waves on the earth are called Seismic Waves
Define frequency.
How fast the thing is
Define amplitude.
the height of the wave
What kind of wave travels by squeesing and spreading? (give an example)
Sound waves, compression waves
What is it called when a wave bounces back and comes back to the source?
It is called Reflection
What is Sonar?
Using sound waves to tell how far things are
